What is the best scenario to close current budget and create new one for next year with minimal impa

Dear All,

 

Please advise with the best scenario to close current budget and create new one for next year with minimal impact on open purchase orders?

 

Details;

If we are going to close current budget at 31-Mar-2012 to create new one, within same time we have hundreds related to current budget.

# Should we keep current budget open to grantee stable performance for related Pos till it’s completely processed?

# What is the impact on budget accounting journals for open Pos if current budget has been closed?

# Should we close open PO and create new ones? If Yes, is there any technical way to do that instead of re-enter data manually?
